PeaZip introduces
some concepts to improve the way archiving-related tasks are handled,
bridging the gap between GUI and command line based software.</span><span

            <ul style="text-align: justify;">
              <li><span style="font-weight: bold;">Save archive layout</span>:
archive layout is
a
list of object scheduled to be archived or extracted.
When creating a new archive or when extracting existing archives, files
and folders can be added to the file archiving or extraction layout
which is
visible on the bottom of the first tab of archiving and extraction
interfaces. Layout can be saved (and edited as a text
file), a saved layout can be added to the
current archiving or extraction layout and PeaZip will take care to
verify if entries
are duplicate and if they accessible. Layouts make easier to define,
merge,
handle, maintain and edit with external tools the lists of object to be
archived or extracted (in example, for <span style="font-weight: bold;">backup
                </span>or <span style="font-weight: bold;">restore </span>purpouse).</li>

PeaZip uses Open Source components from 7-Zip/p7zip, FreeArc, and other
state of art Open Source software to offer the same GUI frontend to
create,
browse, test and extract 7z and ZIP archives under Linux and MS Windows
as
well.<br>
PeaZip for Linux/BSD is desktop-neutral so it can be used either under
Gnome or KDE desktop environment, or also other desktop managers.
System integration mechanisms relies on FreeDesktop standards and
requires a compliant environment, such Gnome and KDE, but basic
file archiving operations are not affected.<br>
PeaZip can<br>
            <ul style="text-align: justify;">
              <li>create single or separate archives</li>
              <li>add/remove
files from existing archives</li>
              <li>convert existing archives to another format (in
example
convert a RAR file in a
ZIP or 7Z file)<br>
              </li>
              <li>extract multiple archives at once<br>

            <div style="text-align: justify;"> <big>FAQ: does
PeaZip supports drag and drop?</big><br>
            <big> <br>
            </big> </div>
            <a href="screenshots-peazip-3.html">Drag and drop</a> is
supported on MS Windows systems. <br>
PeaZip can perform drag and drop <span style="font-weight: bold;">from
the
system to the
application</span>, for adding files to new archive layout or for
opening existing archives dragged to the application, and drag and drop
            <span style="font-weight: bold;">from the application to
the system</span>, for file copy and for extraction form archives.<br>
By default the application uses improved native Windows drag and drop
mechanism,
but optionally it can use its own custom drag and drop implementation,
from Options &gt; Settings &gt; General.<br>
Advantage of PeaZip's drag and drop (both types) is that the
application doesn't need to copy
files to system's temporary path on drag&amp;drop operations, speeding
up the operation if large files are involved (especially noticeable
if files are not in the same volume of system's temp directory) and
don't risking to lowen the security of the operation if the system's
temp folder has security policies different from the ones of the
intended output destination.<br>
PeaZip free archiving utility is not yet integrated with Windows drag
and drop's context menu
handler (but it is integrated with rightclick's context menu for
zipping, unzipping and advanced operations).<br>

            <br>
            <big>FAQ: is PeaZip
faster/slower than...
does
it compress
better than... ?</big><br>
            <big> </big><br>
            <big> </big>Being PeaZip a frontend application, each time
an archive
is
queried
interprocess communication is involved: if the program / the
input path / the output path is on a slow network or slow unit this may
bring a slowdown.<br>
But most of the time is usually spent on file archiving / extracting
operations; in this case PeaZip is as fast as the invoked application
(7z, which is command line 7-Zip
executable, Paq,
Pea, UPX etc...), which
performance is mainly bound to the algorithm and the data compression
level
involved, being the underlying executables good and efficient
implementations.<br>
PeaZip features extremely fast operations, as tar/untar, split/merge
files, create archives with "store" compression level, quite fast
operations (in example Deflate based algorithms, like in gzip
compression),
slow/quite slow
operations (when bzip2, LZMA, PPMd,
unrar, unace are involved), up to very slow operations when PAQ at
highest compression levels are used.<br>
Currently, <a href="peazip-compression-benchmark.html">fastest
compression</a> (faster than any benchmarked archiver utility) is
attained with Google's Brotli and Facebook's Zstandard algorithms.<br>
A wide range of performances and compression levels can be attained
using PeaZip, the point is in chosing the right balance between the two
factors.<br>
Enforcing data security employing <span style="font-weight: bold;">cryptography
            </span>raises a little the
computing power usage, but on average compter the impact of this factor
is usually negligible; decryption
of protected archives is usually even
faster than encryption.<br>
            <br>
            <br>
            <big>FAQ: where does
compressed and
extracted
files go?</big><br>
            <big> </big><br>
            <big> </big>By default PeaZip prompts to zip / unzip in
the same
path of the
input object, but in archiving and extraction interfaces the Output
group allows to set the output path.<br>
The button on the right of the output address bar opens a standard
output selection dialog, while on the left the button shows a dropdown
menu allowing to select an output path from various pre-sets: system's
paths (inlcuding: current item's path, the last used path, desktop,
documents etc...), paths of bookmarked elements, and recently visited
paths (paths visited in the current session, and paths of previously
created or extracted archives). From this menu It is also possible to
set a default custom output path.<br>
UPX is the only exception from that mechanism since it always compress
the input executable file in place.<br>
In Options &gt; Settings first tab it is available the option "Open
output path when job completes".<br>
Otherwise iin the same tab is available the PeaLauncher options
dropdown menu: select "Always keep open to inspect job report" to be
able, alongside other features, to click "Open output path" button
after the job is completed - otherwise by default the job's window will
auto close if no error is reported.<br>

application
seem
not responding /
is slow on startup?</big><br>
            <big> <br>
            </big> </div>
PeaZip may be
performing
lengthy operations which needs to wait completion; in example PeaZip
may be
querying the archive for browsing (especially when flat mode is used on
archives containing many files) or adding / removing files from
archives (needed time depends on the size of the objects and
compression options), or querying the system about files and folders
to be added to archive layout.<br>
Any time a potentially lengthy operation is requested the cursor is
changed to horglass and, when possible, an animation is performed to
inform the user that the operation is running and is needing some time
to be completed.<br>
On startup, PeaZip query the mounted units, so it can be slowed down
if, in example, the system features remote units over a slow network,
or has
defective drives, or slow removable units (like CD/DVD) are being
loaded in the same time.<br>
Another potential source of slowness, both for PeaZip and underlying
backend processes, may be slowed-down disk subsystem, i.e. by high
degree of fragmentation, or cuncurrent disk usage by
antivirus/antimalware (especially if inspecting program's or work
files), p2p, file indexing programs (like Google Desktop, Picasa etc),
system
updates, paging, etc...<br>
[to run disk-bound speed tests, please take in account that on most
systems files are cached after first usage, so becomes accessible in
less time in following tests]<br>
Some algorithms featured by PeaZip free archiver (PAQ, ARC and 7Z at
highest level of
compression...) requires big amounts of memory, so it is recommended to
avoid extreme settings which results in the system to page to disk,
that is some orders of magnitude slower than RAM.<br>

PeaZip free archiver can be integrated to
Microsoft Windows system in the following ways<br>
            <div style="text-align: justify;"> </div>
            <ul style="text-align: justify;">
              <li>You can rightclick on an object or a group of
objects
and use the PeaZip's entries in context menu or "SendTo" menu to
directly send input
object(s) to a specified PeaZip's function. </li>
              <li>You can drag object(s) on PeaZip's program icon
and
the program will try to decide how to handle the object(s) provided by
the user.</li>
              <li>You can drag objects to an open PeaZip instance
to
put the application in full control of the process<br>
              </li>
              <li>You can doubleclick on files of types
associated with
PeaZip to open them.</li>
            </ul>
You can reconfigure
the application's system
integration running the configuration tool in Options &gt; System
integration
(which automatically requires administration rights if needed), or
selecting <span style="font-weight: bold;">"Custom installation /
Configuration"</span>
in the installer to access to more options.<br>
            <br>
PeaZip run on any full Win32 Microsoft Windows desktop system (or
compatible, as Wine and ReactOS) for any type of personal computer or
tablet (recent releases GUI is designed to be touch-friendly in terms
of clickable area and functions discoverability), so at current level
of development is not known of being possible to run it on Windows
RT-only devices. <br>

PeaZip is a standalone, almost
self contained zip / unzip application: you can unpack peazip_portable
package
(.tar.gz) in any path and just click on peazip binary; see
FreeDesktop_integration folder in program's path to know how to
integrate PeaZip with the desktop environment (Gnome, KDE...).<br>
            <div style="text-align: justify;">Distribution-specific
packages of PeaZip were also built from Linux
communities, and some I'm aware of are linked on PeaZip for Linux
download page too.<br>

replaced with respective 64 bit counterpart, but please remember that
any 32 bit executable
will need <span style="font-weight: bold;">ia32-libs</span> to be
installed in order to to run on a 64 bit system.<br>
On ARM systems PeaZip can be compiled as ASM parts featured in some
units for performances, can be replaced by pure Pascal alternative
code, see <a href="peazip-linux-arm.html">PeaZip for ARM Linux</a>
for
example.<br>
            <br>
            <span style="font-weight: bold;">Widgetsets </span><br>
PeaZip free archiver is a cross platform and cross widgetset
application, meaning it
can be compiled for different systems and widgetsets.<br>
Precompiled binaries Linux packages are built for GTK2 and Qt, which
offers
modern look and feel and very functional system dialogs. <br>
PeaZip Portable for Linux can be used as alternative to native packages
on BSD systems, due to binary compatibility provided by BSD systems to
Linux executables.<br>
PeaZip Portable for BSD contains natively compiled (i386, GTK2) peazip,
pea, pealauncher, and p7zip executables, providing most of the
program's funtions are performed by native binaries, for other
backends, Linux binaries are used.<br>
Many other operating systems and widgetsets are supported by Lazarus,
the IDE used for
PeaZip's development, including GTK1, WindCE, fpGUI and Carbon. If
you want to compile PeaZip from sources see <a
 href="peazip-free-archiver.html">notes for developers</a>.<br>
            </div>
            <br>
            <span style="font-weight: bold;">How do I make my
system aware of
PeaZip
functionalities?</span><br>
PeaZip installable packages authomatically create application's icon,
list PeaZip in available applications and create some <span
 style="font-weight: bold;">KDE </span>ServiceMenu
entries to reach most used program's functions (archive, open, extract
here, extract to new folder).<br>
FreeDesktop_integration folder (featured both in installable and in
standalone versions) contains .desktop files and simple instructions to
add PeaZip to start menus and context menus of desktop environments
following the FreeDesktop standards (like Gnome and KDE), and Nautilus
scripts folder which can be manually copied to user's Nautilus script's
folder
to add PeaZip's functionalities to <span style="font-weight: bold;">Gnome</span>'s
context menu.<br>
            <br>
            <span style="font-weight: bold;">What if I cannot run
PeaZip due
to unresolved
dependencies.</span><br>
If the system report missing libraries the first time you are running
PeaZip binary, you can generally find missing libraries on your
installation media or you can search them online using your
installation or update manager,
or even in a web based .rpm or .deb repository; generally missing
libraries are standard, well known and widely available gtk/gkd
components (the most common is libgdk_pixbuf library).<br>
            <br>
            <span style="font-weight: bold;">What
are hardware/software prerequisites?</span><br>
PeaZip should run on x86-compatible CPU due to some performance
critical sections written in ASM, but pure Pascal replacements exists
for those units, allowing to port PeaZip to other architectures (i.e.
ARM).<br>
CPU and, mainly, RAM requisites are
bound top the chosen algorithm and compression level, ranging to few KB
for simpler algorithms (like when storing files without compression in
tar/gz/zip formats) to above than a GB for most powerful and complex
algorithms at highest compression level, like LZMA, PPMd and PAQ).
Needless to say, it is the choice of the file compression algorithm the
most
important factor in determination of job's speed, even if usually the
most advanced algorithms are also the ones which scales better in
performances in multicore enviroments.<br>
As for software prerequisites, all needed software invoked by the
frontend is included in PeaZip packages (being available under suitable
licenses, as open source or royalty free) so no custom package is
needed to be installed to make PeaZip work (with the possible exception
of some standard gtk/gdk related libraries needed to run PeaZip,
PeaLauncher and Pea binaries, which may miss in some system, but are
well known,
trustable and widely available).<br>
If you don't want non open source software in your system, like
unrar.so (which brings specific license restrictions about reverse
engineering) or unace binary (closed source, royalty free), you simply
need to delete them from /res/ path in program's folder.<br>

support for Carbon widgetset is alpha (a solution could be
using alternative libraries, as Qt, but I would prefer the native,
default widgetset), and moreover I can rarely have full access to OSX
systems; however the Lazarus support for OSX is quickly progressing,
and my interest in porting PeaZip to OSX platform remains very high.<br>
I hope to be able to deploy PeaZip free archiver for OSX in future, and
any help and
feedback from users of Lazarus IDE on Apple OSX will be welcome.<br>
